HOOD.

Application filed June 9, 1924;. Serial No. 718,747.

tor dwellings and other buildings, of the pipeless variety. In this modeof heating, as is well knowiuthe heated air is distributed from a singleradiator or floor register, and the colder air is conveyed to thefurnace through this single floor register or grating. The heated airpasses upwardly through a central air duct and the colder air passes tothe furnace through an annular space around the central hotair duct. Thehood of my invention is designed particularly for use with this type offloor radiator or register and is utilized for the purpose of deflectingthe heated air as it: rises through thehot air duct, and directing,

the currents of heated air across from whence the air currents are freeto radiate in all directions. In this manner the heated air currents areprevented from passing directly from the floor register straight up tothe ceiling as is the custom in installations of the pipeless heatingsys- 1 ical embodiment of my invention wherein the parts are combinedand arranged in ac cordance with the best mode I have thus far devisedtor the practical application of the principles of my invention.

Figure 1 is a perspective view showing the hood in position for use onthe top of a floor register for a pipeless furnace or heating system.

Figure 2 is a vertical central sectional view of the hood.

In order that the utility of the device may readily be understood I haveindicated in Figure 1 the grating or floor register 1 of a pipelessfurnace having a box 2 supported in the floor. As is usually the casethegrating 1 has connected thereto from below a cylindrical, central pipefor the updraft of heated air, and around the central pipe is a spacefor the downdraft of colder air pass ing to the furnace.

The casing 8 of the hood, which may be cylindrical or slightly conicalin shape is of a size and shape to rest upon the grating and cover theoutlet therethrough from the central cylindrical hot-air flue or pipe,and

in the side wall of the casing an outlet or opening 4 is provided forthe hot air currents rising through the flue. Below this opening isprovided a base plate 5 of sufli cient area to cover the entrance to thecold lair flue at this point and thus prevent intermingling of the hotair and cold air currents as they pass from and to the grating. theplate 5 which rests upon the grating is f provided with a flange 6 thatcloses the low er part of the opening 4 and is utilized for attachmentto the casing 1.

The portable hood is fashioned with a pyramidal top 7 having an annularflange 8 the floor,x at its lower edge which is adapted to fit over lthe top of the casing, and is bolted thereto as at 9.

At its apex the top or cover of the casing 85 :is provided with a handle10 for convenience in carrying the hood, and a downwardly inclineddeflecting plate 11 is secured to the flange 8 of the top to direct theheated air currents across the floor as plate may also be used as a footrest if desired when the device is called upon to perform the functionsof a foot warmer.

they pass through the opening 1-. This The deflecting plate is fashionedwith side flanges 12 and a comparatively shallow front flange 18 for thepurpose of reinforcing the deflecting plate as well as for the purposeof guiding the hot-air currents from the register.

The deflecting plate is-rigid with the flange 8 of the pyramidal top 7and is conveniently attached thereto by means of the attaching flanges14 and screw-bolts 15.

If desired the casing 3 may be dispensed -with and the pyramidal top orcover 7 utilized in its stead as the portable hood, which as illustratedin Figure 1 is designed especially for use with the grating when thelatter is used in a corner of a room or hall, or when the grating islocated adjacent to a wall. Under these conditions the device asillustrated in Figure 1 is especially adapted to prevent the hot aircurrents, which usually carry dust, from contacting with the wall of thedwelling and marring the wall paper or finished .lVhen spread to thefour diametrical points as indicatedin Figure 2 the arms of thesupporting device are engaged in complementary cleats or clips-20secured at the underside of the conical hood. l Vhen the casing is notused the hood rests uponthe flanges or feet 17 which as will be observedproject below the bottom edge of 'the flange 8 and also below thedeflectin plate 11 carried by the conical plate 01;

hood, leaving a space around and below? the hood forexit of hot aircurrents from, the register upon which the hoodrests.

The several parts ofthe device are standcomprisin two inte 'ral ieces mabe readily detached if desired and folded as one. The side walls of thecasings, when other elements are detached, may be spread out flat andpiled in stacks, and the deflector plates and base plates mayalso becompactly nested for packing or storing I-lavi-figthus fully describedmy invention, What I :claim as new and desire to secure by LettersPatent is A hood for the purpose described comprising a conical-shaped,flanged top, two pairs of legs within the top and proT'ecting therebelow, said pairs of legs each having integral inclined arms and asingle pivot member for said arms, cleats secured at the underside ofthetop, and a handle for the top.

In testim jny whereof I aflix my signature.
